Protective device for the head and ears of an animal

ABSTRACT

A protective cover device for an animal&#39;s head includes a first portion for securement around the animal&#39;s neck, behind the occiput and at or near the smallest diameter of the neck, and a second portion for covering the animal&#39;s ears that is fastened forward of said first portion and at or near the throat or jaw of the animal. The device may be a flexible/generally-flexible panel with supplemental shaping, stiffening, and/or adjustment systems to cup/fit the ears, to prevent the ears from sliding out of the device, and/or to prevent foreign objects such as cheat-grass or fox-tail, ticks, or insects from reaching the ears. Stiffeners may be added along or beside the central axis, around the front edge, and/or near the animal&#39;s ears, to shape and hold the second portion in a configuration protective of the animal ears and not easily rolled-up or pushed off by a paw/foot.

BACKGROUND OF THE INVENTION Field of the Invention

The invention relates to a protector for a portion of an animal's head.For example, the protector may cover a dog's ears after surgery orinjury so that the ears will be shielded from the environment and thedog's own actions, such as shaking, kicking, or scratching, and willheal more quickly than if left uncovered. The protector may also orinstead be used to protect a dog's ears from ear-bites by other dogs,for example, at a dog park or a kennel. The protector may also orinstead be used to protect a dog's ears from injury, for example, duringtimes of confinement in a kennel or cage where a hematoma or otherdamage may occur during rubbing or impact against the bars or otherstructure of such a kennel/cage. Alternatively, the protector may alsoor instead be used as a preventative device, to keep cheat-grass,fox-tail, seeds, burs, ticks or other arachnids, or insects away fromthe ears or other portions of the head of the animal. Dog owners,hunters, veterinarians, kennel operators, joggers, outsdoorsmen/women,and others who care for dogs or other animals, may benefit from usingthe device on a dog or other animal as a protective and/or preventativedevice.

Related Art

Veterinarians typically provide devices to dog owners, after surgery orinjury on or in the vicinity of the dog's ears, to discourage the dogfrom pawing or kicking the affected or injured area(s). These devicesare typically a “doughnut-shaped” pillow or blown-up ring, which isinstalled around the dog's neck and is so large that the dog cannot kickaround the doughnut device to reach the affected or injured area. Such adoughnut-shaped device has an outer diameter that is a multiple of thediameter of the dog's neck, and, hence, can be quite annoying oruncomfortable for the dog, especially when the dog wishes to lie down orsleep. Another common device provided after surgery or injury is theElizabethan collar, the so-called “cone of shame”, that is installedaround the dog's neck, and flares outward and forward far beyond thedog's head. Again, such a “cone” has an outer diameter that is amultiple of the diameter of the dog's neck and is annoying and/oruncomfortable. Because of the annoyance or discomfort, many dogs willtypically try to remove the doughnut or cone, and, even if they do notsucceed, it becomes a troublesome and worrying problem for the dog andthe owner. Neither of these commonly-used devices is very effective, andespecially is not effective in limiting or preventing ear “flapping”such as is caused by shaking of the head, for example. Thus, suchdevices have limited utility, and can cause slow-healing and/orre-injury of the ear flaps. Neither of these devices is an effectivepreventative device for keeping cheat-grass, fox-tail, seeds, burs,ticks or other arachnids, or insects away from the ears or otherportions of the head of the animal.

Smaller and less obtrusive protective devices have been used, but alsohave limited utility and effectiveness. For example, stocking-caps havebeen used on dogs, with the hope that the hat will cover and cushion theaffect or injured ear(s) and that the dog will cooperate by wearing thehat. Also, cloth or knit tubes or wraps have been stretched and/orotherwise installed over the dog's head, by pulling the tube rearwardover the dog's face, or simply wrapping a fabric strip around the dog'shead, to cover the ear area. Such attempts typically result in the dogquickly pawing the hat, tube, or wrap off of his neck and head. A fewswipes of a paw will typically knock off the hat, or roll up the tube orwrap, to the point where it falls off in the forward direction or rollsrearward off of the ears.

In the patent literature, several devices may be seen for covering orcontrolling an animal's ears. For example, Olvera U.S. Pat. No.4,221,189 discloses a cup and frame system for newly-cropped dog ears.Barnes U.S. Pat. No. 6,314,961 discloses a strap and frame system fornew-cropped dog ears. As the purpose of such devices is to encourage theremaining ear portion to extend upright, such devices extend severalinches above the dog's head and support the remaining ear portions.Carmean, et al. Publication No. 2009/0178628 discloses a compressivehead-band for placement around the dog's head, in a similar manner asdescribed above for the cloth or knit tube. The compressive force of theCarmean head-band may be used to hold the ear back, away from the earcanal. Deutscher, et al.'s U.S. Pat. No. 5,456,215 discloses a cover foran animal's head, with eye-holes for placement around the animal's eyes,wherein the cover extends all the way from near the nose to theshoulders. Mann's U.S. Pat. No. 7,946,256 discloses a cover to protectthe ears from cheat-grass, with an inner shell having ear-slits into andthrough which the dog's ears are placed, and an outer shell that laysover the inner shell covering the ears as they protrude through theinner shell.

The inventor is not aware of any prior art dog ear protective coveringsthat are effective, safe, easy-to-install, comfortable for a dog duringinstallation, and comfortable for the dog to wear over extended periodsof time, including lying down and sleeping. The inventor is not aware ofany prior art economical and effective device for limiting or preventing“ear flapping” that is so problematic for injured or healing ears. Thepresent invention meets multiple or all of these needs.

SUMMARY OF THE INVENTION

The invention comprises a protective cover device for a portion of ananimal's head. The protector may cover a dog's ears after surgery orinjury, for protection of a dog's ears from ear-bites by other dogs, forprotection of a dog's ears from injury, and/or for being a preventativedevice to keep cheat-grass, fox-tail, seeds, burs, ticks or otherarachnids, or insects away from the ears or other portions of the headof the animal. The preferred protector includes adaptation forsecurement around the animal's neck to prevent the device from easily oraccidentally being removed, and adaptation for covering, cupping, and/ormildly compressing the animal's ears. The preferred protector includesadaptation for shaping and/or adjustment, such as stiffened regions orstiffeners, preferably along or beside the central axis, and in certainembodiments around the front edge of the device and/or in the earregions, to shape and/or hold the second portion in a configuration thatis protective of the animal ears and that cannot be easily rolled-up,scrunched-up, or pushed off by the animal's paw/foot.

In certain embodiments, the device comprises a first portion forsecurement around the animal's neck, behind the occiput and at or nearthe smallest diameter of the neck, and a second portion for covering aforward portion of the animal's head. Preferably, the second portioncovers the animal's ears and is fastened forward of said first portionand at or near the throat or jaw of the animal. The first and secondportions may be connected together as parts of a generally flat panelthat is flexible or generally flexible for being wrapped around the neckand the occiput-ear-cheek region, respectively. The first portionsnuggly fitting around the animal's neck secures the device to theanimal's head and prevents the device from easily or accidentally beingremoved. The second portion preferably covers, cups, and/or mildlycompresses the animal's ears, in order 1) to shield surgery-affected orinjured head/ear(s) and to retain them substantially or entirely intheir natural positions with limited or minimal movement relative to thehead of the animal, and/or 2) to cover the head/ears for preventingforeign objects, such as cheat-grass or other plant matter, ticks orother arachnids, or insects, from reaching/entering the head/ears. Thesecond portion is adapted in certain embodiments to be used on a dog,and to fit closely or tight enough 1) to limit or prevent movement ofthe ear flaps (pinna) caused by the animal's own movement or othercauses, because “flapping” of the ears may be harmful during healingfrom surgery or injury and/or 2) to limit or prevent invasion of saidforeign objects onto/into the head/ears.

The device may comprise or consist essentially of a single panel shapedso that said first portion is connected to the second portion at arelatively narrow junction at or near a central axis, with both firstand second portions extending separately from each other away from saidjunction mainly transversely to the central axis, so that right and leftstraps or wings of each of the portions are fastenable to formsubstantially separate, forward and rearward loops/wraps. Supplementalshaping and/or adjustment of the device may be done to cup and/or fitthe ears well, and/or to prevent the ears from sliding out from underthe device. Supplemental shaping and/or adjustment may include providingcupped-shaped ear regions in the second portion by sewing, gathering, orother forming techniques. Supplemental shaping and/or adjustment mayinclude providing supplemental stiffened regions or stiffeners,preferably along or beside the central axis, and in certain embodimentsaround the front edge of the device and/or in the ear regions, to shapeand/or hold the second portion in a configuration that is protective ofthe animal ears and that cannot be easily rolled-up, scrunched-up, orpushed off by the animal's paw/foot. Supplemental shaping and/oradjustment may comprise independent adjustment of the tightness of eachof the forward and rearward loops/wraps, for example, by providingadjustable and/or moveable fasteners. Supplemental shaping and/oradjustment may comprise adjustment of the front-to-rear length and/orside-to-side width of the device to fit a variety of animal heads.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Referring to the Figures, there are shown several, but not the only,embodiments of the invented protection device for animals, whichcomprise a first portion for securement to the animal neck, and a secondportion for securement to the animal head forward of the neck. The firstportion is preferably an integral portion of the main body (or mainpanel), and may be called a “neck portion” or alternatively a “collar”.The second portion preferably is also an integral portion of the mainbody (or main panel), and may be called an “ear portion”, oralternatively a “head portion” or “hood”. The neck portion is preferablyflexible and bendable, so as to be wrappable and tightenable around theneck of the animal. The ear portion is preferably also flexible andbendable (or substantially flexible and bendable) to an extent that itmay be wrappable and fastenable around the animal's head at or near theears. Included in “substantially flexible and bendable” in certainembodiments is that the ear portion may comprise stiffeners or otherrigidizing portions that are relatively stiff compared to the flexibleand bendable main body of the device, and that resiliently urge thedevice into the desired shape, for desired containment/shielding of theears and/or to prevent rolling-up or “scrunching” of the ear portion,off of the ears or head, by the animal.

Certain embodiments may comprise the ear portion of the device being apre-shaped, generally-inflexible hood at its top and sides, withflexible straps or other extensions to fasten the hood at the throat/jawof the animal. Such pre-shaped, generally-inflexible embodiments areless preferred, however, because fitting such a device to variousanimals would be more difficult than fitting the flexible orsubstantially-flexible embodiments, and because such devices would beless-soft and less-comfortable.

Certain embodiments of the device may be sewn or otherwise formed, fromfabric, polymeric, or other sheet materials, into a one or multi-layerconstruction taking the general shape of a single panel that is, atleast in part, flexible and bendable. For example, an easily-washed anddurable fabric may be used. Said panel may have pockets, inserts, hookand loop fastener additions, appliques or other multi-layer portions,tucks, gathers, and seams, if desired to create cupping of the earsand/or shape and position control; still, many embodiments may bedescribed as a single, generally-planar panel.

FIGS. 1 and 2 show top and bottom views, respectively, of one embodimentof the device 10. FIGS. 3 and 4 show a side view and a cross-sectionalview of the device 10 in its folded/wrapped and fastened configuration,and FIG. 5 shows a side perspective view of the device 10 being worn bya dog. A central panel portion 12 extends between a front edge 38 (atthe bottom of the page) and a rear edge 39 (top of page) and compriseslongitudinal central axis CA. The central panel portion 12, which duringuse extends longitudinally along the top of the animals head from nearerthe nose to nearer the shoulders, supports or “carries” the portionsthat extend transversely from it to encircle the animal's neck and toencircle the animal's head, namely, the neck portion NP and the earportion EP, respectively.

The neck portion NP (or “collar”, or “neck loop”, or “rear portion”)connects to the ear portion EP (or “hood” or “head loop” or “ear loop”or “front portion”), at junction J, at and adjacent to the central axisCA. The neck portion NP extends rearward from junction J andtransversely away from the central axis CA, forming right and left neckstraps 14, 16. “Right” and “left” here are used in a way thatcorresponds to the dog's right and left cheeks, for example, rather thanthe right and left of the drawing page. Neck straps 14, 16, therefore,are each an elongated, generally rectangular, protrusion from thecentral panel portion 12 at or near the rear extremity of the device 10.Hook and loop fasteners 15 and 17, or other fasteners, are providedat/near the ends of the right and left neck straps 14, 16 for preferablyadjustably fastening the straps 14, 16 around the animal's neck, at ornear the smallest diameter portion of the neck, preferably sufficientlytightly that the neck portion stays in place on the neck in spite of theanimal's actions such as rubbing against other objects. The preferredadjustable fastener(s) of the neck straps 14, 16, for example hook andloop fastener, provide about 4 inches of adjustment in the circumferenceof the fastened neck portion; this adjustability allows a single sizeand style of device to fit the necks of many different dogs, forexample. As shown in FIG. 1, each of the right strap 14 and left strap16 has an inner end at said central axis CA and a strap outer end 14E,16E, with each of the right and left straps 14, 16 extending outtransversely from the central axis CA, so that a right strap axis 14Aextends transversely from said central axis CA to the right strap outerend 14E and a left strap axis 16A extends transversely from said centralaxis CA to the left strap outer end 16E, and the right strap axis 14Aand left strap axis 16A are each perpendicular to the central axis CA.

The ear portion EP extends forward from junction J and transversely awayfrom the central axis CA, forming right and left wings 24, 26. Right andleft wings 24, 26 may be generally triangular protrusions, eachcomprising a triangle-point/end distanced from the central axis CA thatis the outermost extremity of each wing 24, 26. The front edges of eachwing 24, 26 preferably align with the front edge of the central panelportion 12 to form a curved front edge 38, which is the front-mostextremity of the device 10. Hook and loop fasteners 25 and 27, or otherpreferably-adjustable fasteners, are provided at/near the ends of theright and left wings 24, 26 for fastening the wings 24, 26 together atconnection 28 underneath the animal's head (FIG. 5). Specifically, thewings preferably extend from at or near the largest-diameter of theanimal head, which is typically at the occiput, down over each ear andalong each cheek, to fasten at the throat/under-the-lower-jaw of theanimal. Preferably, the ear portion EP is tightened sufficiently toprevent the animal from pawing the lower half of the ear portion EPforward and up around the animal's snout and to prevent the animal frombeing able to push/thrust a paw between the device and the animal'sskin. The preferred adjustable fastener(s) of the wings 24, 26, forexample hook and loop fastener, provide about 4 inches of adjustment inthe circumference of the fastened ear portion; this adjustability allowsa single size and style of device to fit the head of many differentdogs, for example. Each of the right wing 24 and left wing 26 has aninner end at said central axis CA and a wing outer end 24E, 26E, witheach of the right and left wings 24, 26 extending out transversely fromthe central axis CA, so that a right wing axis 24A extends transverselyfrom said central axis CA to the right wing outer end 24E and a leftwing axis 26A extends transversely from said central axis CA to the leftwing outer end 26E, and the right wing axis 24A and left wing axis 26Aare each perpendicular to the central axis CA.

Several features prevent the ear portion EP from being pawed forward orrearward off the head. For example, the secure placement of the neckportion NP around the neck, combined with the connection of the twoportions NP and EP at the top of the head, helps prevent pushing or“scrunching” of the device forward off the head. The preferredstiffening/rigidizing adaptations, along the top of the device(preferably in the central panel portion 12), the front edge of thedevice, and optionally other portions of the sides, helps preventrolling-up or rearward “scrunching” of the device rearward off the earsand head. Thus, dislodging the ear portion EP from its desired locationis unlikely.

Thus, the neck portion NP and the ear portion EP, in use, are fastenedinto two loops or sleeves and are placed on the animal in different,preferably entirely or substantially non-overlapping, non-layeredpositions. For example, as illustrated in FIG. 5, the neck portion NP isrearward of the ear portion EP, with a gap G between the lower regionsof the portions NP, EP where one may typically see a portion of theanimal's neck N. The rearward, neck portion is snug and relatively tightaround the neck of the animal, that is, sufficiently snug/tight tomaintain the device in position relative to the neck and to prevent theanimal from pulling or pushing off the device in a forward direction.Because the neck portion is around a smaller or the smallest diameter ofthe neck, forward from the relatively larger shoulders and rearward fromthe relatively larger head/occiput region, the neck portion is nottypically removable by the animal. The forward, ear portion EP may beinstalled with varying tightness around the occiput-ear-cheek region,for example, as tight as the animal owner or caregiver feels isnecessary to limit or prevent the ears from “flapping”. The ear portionmay be looser than the neck portion in certain embodiments or tighterthan the neck portion in certain embodiments. In certain embodiments, asillustrated by FIGS. 3, 5, 10, 14, 19 and 22, the head loop diameter (DHin FIGS. 3 and 4) may be the same, or substantially the same, as theneck loop diameter (DN in FIG. 3).

Stiffener/rigidizing adaptations, such as plate or strip members, may beused: 1) to control the shape and position of the ear portion EP andhence the contact/pressure of the ear portion EP on the ears or oncertain portions of the animal's skin, and/or 2) to prevent rolling-upor scrunching of the ear portion by pawing the ear portion or byrolling/rubbing against the ground or another object. Thestiffener/rigidizing adaptations, such as the plate or strip members,are preferably: 1) more rigid than the surrounding material/portions ofthe device, for example somewhat rigid and somewhat inflexible, 2) butnot so rigid and inflexible as to be harmful or hurtful to the animal,while 3) being slightly bendable and resilient. For example, said plateor strip members may each be a sheet of high density polyethylene thatlies substantially on a sheet plane (being only a few millimeters thickfor example and much longer and wider than thick). Each plate or stripmember “sheet” may temporarily be forced to bend out of its sheet planebut will resiliently return to lying in said sheet plane (to be planaror substantially planar) when the force is lessened or removed. Thus,the resilient stiffener/rigidizing members/regions tend to return totheir original shape and position when the animal attempts to paw, push,or rub the device off its head/ears. This resiliency limits or preventsthe animal's pawing or other actions from being able to scrunch orotherwise dislodge the device from its preferred location described inthis document and shown in the figures. The animal may paw or push thedevice a few times, but the stiffener/rigidizing member/regionsresiliently “spring” back to the desired position as soon as the animalspaw or force is relaxed or withdrawn; soon, most animals get used to thedevice and stop trying to remove it. The resilient stiffener/rigidizingmembers/regions may comprise integral stiffened regions ofrelatively-stiff material that is attached to adjacent more-flexible(less-stiff) material by sewing, adhesive, or otherattachment/connection means, and/or separate plates/strips ofrelatively-stiff material that are inserted into or between layers ofthe surrounding more-flexible (less-stiff) material.

Preferred stiffener/rigidizing members comprise one or more plates 13may be sewn or otherwise provided in/on the central panel portion 12, inorder to make the central panel portion 12 a generally planar,non-rollable and non-scrunchable region at the top of the animal's head.Further, in certain embodiments, additional strips 34, 36 are sewn orotherwise provided in the wings 24, 26, which strips 34, 36 may be morerigid than the surrounding material of the device, to shape the regionfor optimum protection/retention of the ears and/or to further preventsaid rolling-up or scrunching. The strips 34, 36 preferably each extendfrom a rearward location at or near the plate 13 and extend forward andslightly downward, toward the front edge of the wings. This rearanchoring/positioning and generally horizontal, or “forward anddownward” slanting of the strips, will tend to cross over the ears andrigidize the ear portion for roll-up/scrunch prevention. Additionalstrips 35, 37 are preferably used at or near the front edge of eachwing, to further form/control the shape of the ear portion and toresiliently resist the animal's actions and rubbing against otherobjects from dislodging the ear portion. The plate 13, strips 34, 36,and/or strips 35, 37 adapt certain embodiments of ear portion to feeland act like a hood rather than a tight compression sock or band.

The plate 13, strips 34, 36, and/or strips 35, 37, may be connected toouter surfaces, or placed inside pockets or other spaces between layers,of fabric that are used in construction of the device 10 according toconventional sewing techniques, for example. Connecting the plate 13,strips 34, 36, and/or strips 35, 37 to the inside surface of the device,and/or in a way that exposes them at the inner surface of the device tothe animal's skin, is less desirable because the exposed plate(s) orstrip(s) might tend to rub or poke the animal.

To further shape and fit the device 10 to the animal's head, fabriclayer(s) may be folded over at edges and/or seams, and tucks 44 orgussets may be provided. The tucks 44 are desired to create a slightcup-shaped curvature in each side wing 24, 26, for cupping/cradling eachear.

FIGS. 6-11 illustrate an alternative embodiment of the device 110, whichis made similarly to, and may be used according to the same or generallythe same methods as, device 10. FIGS. 6 and 7 show top and bottom views,respectively, of the device 110, and FIG. 8-10 show installation of thedevice 110 on a dog. Central panel portion 112 extends between a frontedge 138 and a rear edge 139 and comprises longitudinal central axisCA′. The neck portion NP, connects to the ear portion EP at junction J′,at and adjacent to the central axis CA′. The neck portion NP′ extendsrearward from junction J′ and transversely away from the central axisCA′, forming right and left neck straps 114, 116 that are eachelongated, generally rectangular, protrusions from the central panelportion 112. Hook and loop fasteners 115 and 117, or otherpreferably-adjustable fasteners, are provided at/near the ends of theright and left neck straps 114, 116 for fastening the straps 114, 116around the animal's neck, at or near the smallest diameter portion ofthe neck.

The ear portion EP′ extends forward from junction J′ and transverselyaway from the central axis CA′, forming right and left ear wings 124,126 that are each generally triangular protrusions comprising a trianglepoint/end distanced from the central axis CA′ as the outermost extremityof each wing 124, 126. Hook and loop fasteners 125 and 127, or otherpreferably-adjustable fasteners, are provided at/near the ends of theright and left wings 124, 126 for fastening the wings 124, 126underneath the animal's head at connection 128. The ear portion EP wrapsaround the animal's head, extending across (at or near) thelargest-diameter of the animal head, which is typically along theocciput, over each ear and along each cheek, to fasten at thethroat/under-the-lower-jaw of the animal.

Similarly to device 10 of FIGS. 1-5, the neck portion NP′ and the earportion EP′ of device 110, in use, may be described as fastened into twoloops or sleeves and are placed on the animal in different, preferablynon-overlapping, non-layered positioned. The rearward, neck portion issnug and relatively tight around the neck of the animal, that is,sufficiently snug/tight to maintain the device in position relative tothe neck and to prevent the animal from pulling or pushing off thedevice. Because the neck portion is around a smaller or the smallestdiameter of the neck, forward from the relatively larger shoulders andrearward from the relatively larger head/occiput region, the neckportion is not typically removable by the animal. The forward, earportion may be installed with varying tightness around theocciput-ear-cheek region, and may be only as tight as the animal owneror caretaker feels is necessary to limit or prevent ear flapping, forexample, with a comfortable, mild pressure against the ears. The neckportion is substantially or even entirely used to maintain the device onthe animal, with the ear portion's connection/integral-attachment to theneck portion at the top of the animal's head keeping the ear portion inplace relative to the neck portion and, hence, the animal's head. Thefastening of the ear portion at the animal's throat helps keep the earportion in place as well, but said connection at the top to the neckportion, and the preferred stiffener/rigidizing elements, prevent ananimal from being able to paw the ear portion off, and allows therelatively loose or at least comfortable tightness of the ear portion.

In a similar way and of similar materials as in device 10, stiffenerplate 113 may be sewn or otherwise provided in/on the central panelportion 112, making the central panel portion 112 a generally planar,non-rollable, non-scrunchable region at the top of the animal's headduring use of the device 110. See FIG. 11, grouped on the same page asFIG. 14. As discussed above, the plate 113 is slightly flexible, toprevent injury to the animal, but is resilient, to return to itsoriginal shape and position, in order to limit or prevent the animal'spawing or other actions from being able to scrunch or otherwise dislodgethe device from its preferred location.

An adjustment strap 150 is provided transverse to the central axis CA indevice 110, for further fitting of the device 110 to the animal's head.This strap adjustably connects by hook and loop fasteners or otherpreferably-adjustable fasteners to regions on each side of the centralportion 112, and by adjusting the position of the ends of the strap (forexample, hook patches) relative to said regions (for example, looppatches), the right and left side wings in those areas are pulledtogether. Said pulling together of said regions serves to adjust thewidth of the ear portion, or, in other words, effectively reduce thedistance between the “triangle-point/end” outermost extremities of eachwing 24, 26 and, hence, reduce the effective circumference of the earportion “loop”. For example, there may be enough variability ofplacement of the strap 150 on the patches 151, 152, to pull the patchestogether by up to 1-2 inches preferably, or even up to about 3 inches,for example. This will make the ear portion fit the animal headsubstantially better in that area, for example, keeping the ears fromsliding or falling rearward toward or out from the rear of the earportion.

Thus, the preferred device comprises an ear portion that tends to feeland act like a hood rather than a tight sock, band, or wrap. This may beaccomplished by a combination of selected fabrics, the shape and contourof the ear portion as formed/sewn and stiffened in selected regions,and/or adjustments in the dimensions of the ear portion when fitted onthe animal. In addition to (or instead of in certain embodiments) theplates, strips, and straps discussed above, other plates, strips, orstraps, or other shape-forming structure may be used to form/control theshape and resiliency of the ear portion. In certain embodiments, insteadof inserting/attaching said stiffener plates and strips into/on flexibleand foldable fabric, the device may be made of multiple panels ofdifferent materials that have different rigidities and resiliencies.Conventional sewing techniques, for example, may be used to constructthe device with stiffeners inserted or attached to flexible fabric,and/or from multiple panels and multiple materials.

FIGS. 8-10 illustrate how the device 110 may be placed on a dog. As withdevice 10, device 110 is adapted to limit or prevent the ears fromflapping, or to limit or prevent foreign objects from reaching ears orother portions of the head of the animal. One may see how the forwardportion, the ear portion EP′, is forward relative to (and essentiallyseparate from except for the connection at junction J′) the neck portionNP′. A gap G typically exists between the ear portion EP′ and the neckportion NP′, so that a portion of the animal's neck N typically may bevisible between the two portions EP′, NP′. The fastener(s) for the earportion are forward and spaced from the fastener(s) for the neckportion. The two portions EP′ and NP′ typically and preferably do notlie on top of one another or otherwise overlap, or at least preferablydo not overlap more than a small amount near the neck of the animal.

Thus, in both device 10 and device 110, one may say that a portion of asingle panel encircles the animal's neck and another portion of thesingle panel encircles the animal's head, the single panel (and each ofsaid portions) preferably not comprising any ear holes or any eye holes.Preferably, none of the device 10, 110 extends under an earflap (pinna)of the animal, that is, between the earflap (pinna) and the side/cheekof the animal. The ears of the animal are preferably and typically notinserted through any hole/slit/hole and need not be touched or handledby the person installing the device 10, 110 on the animal. There ispreferably and typically no frame structure or guide structure thatlifts the animal's ears, and, hence, the device 10, 110 would typicallynot be used for supporting or controlling cropped dog ears.

FIGS. 12 and 13 illustrate certain features, of the main panels ofdevices 10, 110, respectively, which provide a good fit and effectiveperformance in terms of retaining the device 10, 110 on the animal andlimiting or preventing potentially-damaging ear-flapping and/orpotentially-damaging plant, arachnid, or insect access. The neck portionNP, NP′ straps 14, 16, 114, 116 extend straight and transversely fromthe central portion, with straight front edges 46, 146 being generallyperpendicular to the length of the central portion 12, 112 and generallyparallel to the longitudinal centerline CL, CL′ of the straps 14, 16,114, 116. Ear portions EP, EP′ have rear edges 47, 147 that extend outand forward from the central portion, so that angles A, A′ between thefront edges of the neck portion NP, NP′ and the rear edges of the earportion EP, EP′ are in the range of about 15-60 degrees, and morepreferably in the range of 15-45 degrees, and most preferably in therange of 20-35 degrees. As the front edges 46, 146, are generallyparallel to the centerline CL, CL′ of the straps, angle B, B′ is thesame or about the same as angle A, A′, and, hence, about 15-60 degrees,and more preferably in the range of 15-45 degrees, and most preferablyin the range of 20-35 degrees. Angle C, C′ between the rear edges 47,147 of the ear portions EP, EP′ and the front edges 38, 38′ (beingapproximated by a line FL from the end of the ear portions to the centerC of the central portion) is about 25-60 degrees, more preferably 30-55degrees, and most preferably 40-50 degrees.

It may be noted in FIG. 12 that the width of the narrowest region W1 ofthe ear portion EP is wider than the width W of the central portion 12.In FIG. 13, the width of the narrowest region of the ear portion EP′ isabout the same as the width W of central portion 12. It will be apparentfrom viewing FIGS. 12 and 13, in combination with FIGS. 1, 2, 6, and 7,that the connection junction J, J′ that connects the neck portion NP tothe ear portion EP has width W1 in FIG. 12 and width W in FIG. 13, andthat these widths W1 and W are both much smaller than the width WN andwidth WE of the neck portion and ear portion, respectively, illustratedin FIG. 12. Preferably, the width W1, W of the junction J, J′ istransverse to the central axis and less than 30% (or preferably lessthan 25%, or most preferably 10-20%) of the width of each of the neckportion and the ear portion. The ear portion EP′ in FIG. 13 is connectedto the neck portion NP′ by a piece of the central portion 112, resultingin their being a strip (distance D) of central portion 112 between thetwo portions EP′ and NP′. In certain embodiments, this distance D may bechanged or adjustable to distance the ear portion from the neck portion.

The above relationships and angles are examples of configurations andshapes that result in a neck collar/band that encircles the animalsneck, with a substantially separate but centrally-connected protectivehood extending across the top of animal head and down along the ears.The separate structure of the neck portion and ear portion allow them tobe separately and specially-adapted for their two different purposes.Further, space between the neck portion NP, NP′ and the ear portion EP,EP′ provides a comfortable fit, without unnecessary and possiblyuncomfortable, cumbersome, or interfering fabric or other structurebeing in said space.

FIG. 14 is a portrayal of an alternative embodiment of the device 200,again showing the adaptations wherein the ear portion is substantiallyseparated from the neck portion but is connected to the neck portion atthe top of the head/neck. Therefore, a portion of the animal's neck N isagain visible in the gap G between the portions. This device 200 is madeof fabric, or has fabric areas, that serve as loop fastener to cooperatewith hook patches provided on ends of the straps/wings of the device.Therefore, in such an embodiment, an end of the neck portion strap maybe fastened in various locations on the outer fabric surface of the neckportion or less preferably on the outer surface of the rear region ofthe ear portion. This variable fastening location Ln preferably extendsa few inches from at or near the rearmost edge of the neck portion tothe rearmost region of the ear portion, as shown by dashed lines and anarrow near Ln. Similarly, an end of an ear portion wing may be fastenedin various locations on the outer fabric surface of the ear portion.This variable fastening location is shown as Le, and is preferably a fewinches along the cheek region of the ear portion, as indicated by dashedlines and an arrow near Le. As may be seen in FIG. 14, it is preferredthat locations for ear portion fastening are all forward of thelocations for neck portion fastening; that is, the Le locations are allforward from a vertical line/plane V, whereas the Ln locations are allrearward from the vertical line/plane V. Some embodiments with thisamount of variability in fastening location are less preferable comparedto those with specifically-placed hook and loop patches, as they mayallow for leeway in installation that may not result in optimumperformance.

FIGS. 15 and 16 are top and bottom views, respectively, of yet anotheralternative device 300. One may understand from viewing these figuresthat this embodiment 300 has much structure, and many features and uses,in common with the earlier-described embodiments. For example, thecentral panel portion extends between a front edge (at the bottom of thepage) and a rear edge (top of page) and comprises a longitudinal centralaxis. The neck portion connects to the ear portion, at a junction, atand adjacent to the central axis extending from the front edge to therear edge of the device 300. The neck portion extends rearward from thejunction and transversely away from the central axis, forming right andleft neck straps 314, 316. Neck straps 314, 316, therefore, are each anelongated, generally rectangular, protrusion from the central panelportion at or near the rear extremity of the device 300. Hook and loopfasteners, or other preferably-adjustable fasteners, are providedat/near the ends of the right and left neck straps for fastening thestraps around the animal's neck, at or near the smallest diameterportion of the neck. Hook and loop fasteners, or otherpreferably-adjustable fasteners, are provided at/near the ends of theright and left wings 324, 326 of the ear portion, for fastening thewings around the animal's ears and cheeks, by fastening at thethroat/jaw area.

Device 300, like certain other embodiments, is mainly formed of flexiblefabric plus adjustable fasteners, and stiffener/rigidizing members.Similarly to the embodiments above, the stiffener/rigidizing members areplates or strips that are much longer and wider than thick, and that areresilient but more rigid than the surrounding materials, for controllingthe ear portion shape and pressure on the animal's ears and/or toprevent rolling-up or scrunching of the ear portion, as discussed above.The plates 313, 313′ may be made of/from a sheet(s) of polymer such ashigh density polyethylene, for example. Particularly preferred in thisembodiment are two parallel plates 313, 313′ (which, due to theirdimensions, could also be called “strips”) that may be sewn or otherwiseprovided in/on the central panel portion of the device 300. Plates 313,313′ are more rigid than the surrounding material of the device, inorder to make the central panel portion generally non-rollable andnon-scrunchable, especially front the front to the back of the device,as discussed earlier in this document. These two plates 313, 313′ arespaced apart slightly and are on each side of the central axis, that is,not lying on or crossing over the central axis, and have been found incertain embodiments to be more effective than a single plate that lieson and crosses over the central axis. These two plates 313, 313′ maypivot in position relative to each other because they are not connectedexcept by virtue of being on or in flexible fabric. The plates tend tolie along-side, but not over, the dog's sagittal crest that runslongitudinally along the top of the dog's head. Lying thus on each sideof a the crest/ridge of the dog's head, the plates may pivot to be otherthan co-planar, that is, at an angle to each other, for example, incertain embodiments pivoting to be at an obtuse angle to each otherrather than co-planar, the two plates 313, 313′ tend to stay in placerelative to the dog's head and to be comfortable, while stillaccomplishing the desired utility of preventing rolling and scrunchingof the device by the dog.

Additional relatively-rigid but resilient stiffener/rigidizingstrips/plates 335, 337 may be sewn or otherwise provided in the wings.The strips/plates 335, 337 may be at or near the front edge of the earportion, to further form/control the shape of the ear portion.Additionally, stiffener/rigidizing strips/plates 364 and 366 may beprovided in/on the neck straps 314, 316 for reinforcement and improvedreliability and comfort when the neck straps are fastened around thedog's neck to hold the device 300 in place relative to the dog's head.

An adjustment strap 350 is provided in device 300, transverse to thecentral axis and to the plates 313, 313′, for further fitting of thedevice 300 to the animal's head, similarly as described above regardingadjustment strap 150. Strap 350 adjustably connects to ear portion (forexample, hook patches), on each side of the central portion, and byadjusting the position of the strap (for example, loop patches or loopmaterial all along the length of the strap) relative to said regions,the right and left side wings in those areas are pulled together toshorten the width of the ear portion, and, as discussed above, toshorten the distance between the ends of the wings and the resultingcircumference of the ear portion “loop”. For example, there may beenough variability of placement of the strap 350 on the patches 351,352, to pull the patches together by up to 1-2 inches, or even more, forexample, up to 3 inches or 4 inches. In device 300, the strap 350 andthe patches 351, 352 are on the bottom/inside of the device 300 and sostrap 350 is adjustable by a user from the inside of the device,typically prior to installing the device 300 on the animal.

FIGS. 17 and 18 are top and bottom views, respectively, of yet anotheralternative device 400. One may understand from viewing these figuresthat this embodiment 400 has much structure, and many features and uses,in common with the earlier-described embodiments. For example, a centralpanel portion extends between a front edge (at the bottom of the page)and a rear edge (top of page) and comprises a longitudinal central axis.The neck portion connects to the ear portion at a junction, at andadjacent to the central axis. The neck portion extends rearward fromjunction and transversely away from the central axis, forming right andleft neck straps 414, 416. Neck straps 414, 416, therefore, are each anelongated, generally rectangular, protrusion from the central panelportion at or near the rear extremity of the device 400. Hook and loopfasteners, or other preferably-adjustable fasteners, are providedat/near the ends of the right and left neck straps for fastening thestraps around the animal's neck, at or near the smallest diameterportion of the neck. Hook and loop fasteners, or otherpreferably-adjustable fasteners, are provided at/near the ends of theright and left wings 424, 426 of the ear portion, for fastening thewings around the animal's ears and cheeks, by fastening at thethroat/jaw area.

Device 400, like certain other embodiments, is mainly formed of flexiblefabric plus adjustable fasteners, and relatively rigid but resilientstiffener/rigidizing members, for example made from polymer such as highdensity polyethylene. Particularly preferred in this embodiment are twoparallel plates 413, 413′ that may be sewn or otherwise provided in/onthe central panel portion of the device 400. Plates 413, 413′ are morerigid than the surrounding material of the device, in order to make thecentral panel portion generally non-rollable and non-scrunchable,especially front the front to the back of the device, as discussedearlier in this document. These two plates 413, 413′ are spaced apartslightly and are on each side of the central axis, that is, not lying onor crossing over the central axis, and have been found in certainembodiments to be more effective than a single plate that lies on andcrosses over the central axis. These two plates 413, 413′ may pivot inposition relative to each other because they are not connected except byvirtue of being on or in flexible fabric. The plates tend to liealong-side, but not over, the dog's sagittal crest that runslongitudinally along the top of the dog's head. Lying thus on each sideof a the crest/ridge of the dog's head, and in certain embodimentspivoting to be at an obtuse angle to each other rather than co-planar,the two plates 413, 413′ tend to stay in place relative to the dog'shead and to be comfortable, while still accomplishing the desiredutility of preventing rolling and scrunching of the device by the dog.

Additional stiffener/rigidizing strips/plates 435, 437 may be sewn orotherwise provided in the wings, at or near the front edge of the earportion, to further form/control the shape of the ear portion.Additionally, stiffener/rigidizing strips/plates 464 and 466 may beprovided in/on the neck straps 414, 416 for reinforcement and improvedreliability and comfort when the neck straps are fastened around thedog's neck to hold the device 400 in place relative to the dog's head.

An adjustment strap 450 is provided in device 400, transverse to thecentral axis and to the plates 413, 413′, for further fitting of thedevice 400 to the animal's head. Like straps 150 and 350 discussedabove, strap 450 adjustably connects to regions of the ear portion, oneach side of the central portion, wherein adjusting the position of thestrap relative to said regions can pull the right and left side wings inthose areas together, for reducing the width of the ear portion, inother words, reducing the distance between the outer extremity ends ofthe wings and the resulting circumference of the ear portion “loop”. Forexample, there may be enough variability of placement of the strap 450on the patches 451, 452, to pull the patches together by up to 1-2inches, or even more, for example, up to 3 inches or 4 inches. As withstrap 150 and 350, this will make the ear portion fit the animal headsubstantially better in that area, for example, keeping the ears fromsliding or falling rearward toward or out from the rear of the earportion. In device 400, one may note that the strap 450, and patches451, 452, are on the top/outside of the device 400 and so is adjustableby a user from the outside of the device, for example, after the device400 has been placed on the animal's head.

Device 400 may be seen installed on a dog in FIG. 19, with a schematiccross-section of the device 400 shown in FIG. 20 as would be viewedalong 20-20 in FIG. 19. From these figures and from the discussionearlier in this document, one may understand how the device 400 isinstalled on the dog, and how the strap-based (450, 451, 452) adjustmentsystem will work to provide a good fit for various dogs and/or variousmedical or foreign-object-prevention needs.

An especially-preferred embodiment of the device 500 is shown in FIGS.21 and 22. One may understand from viewing these figures that thisembodiment 500 has much structure, and many features and uses, in commonwith the earlier-described embodiments, but has further refinements inadjustability. Similarly to devices 10, 110, 200, 300, and 400, device500 has a neck portion and ear portion that, in use, may be described asfastened into two loops or sleeves for placement on the animalpreferably in different, preferably non-overlapping, non-layeredpositions on the neck and the head/ears, respectively. The rearward,neck portion comprises neck straps 514, 516 fastenable to be snug andrelatively tight around the neck of the animal, that is, sufficientlysnug/tight to maintain the device in position relative to the neck andto prevent the animal from pulling or pushing off the device, as inearlier-described embodiments. The forward, ear portion may be installedwith varying tightness around the occiput-ear-cheek region. The earportion may be fastened/adjusted to be only as tight as the animal owneror caretaker feels is necessary, with a comfortable, mild pressureagainst the ears for example, to limit or prevent ear flapping and/or toguard against foreign objects from reaching ears or other portions ofthe head of the animal. The fastening of the ear portion around theanimal's head helps keep the ear portion in place as well, but theconnection of the ear portion at the top to the neck portion, and thepreferably-resilient stiffener/rigidizing members/regions, prevent ananimal from being able to paw the ear portion off, and allows therelatively loose or at least comfortable tightness of the ear portion.Stiffener/rigidizing members/regions preferably extend along all ornearly all of the length of the device from the front edge to the rearedge of the device, for example, greater than 70% of said length,greater than 80% of said length, or greater than 90% of said length.Also, stiffener/rigidizing members/regions preferably extend along allor nearly all of the front edge of the device (along the “length”dimension between the wing ends, that is, the end extremities of thewings), for example, greater than 60% of said length of the front edge,greater than 70% of said length of the front edge, or greater than 80%of said length of the front edge.

As in other embodiments described above, the ear portion extends forwardfrom a junction area, at or near the central longitudinal axis CA″ ofthe device 500, serving as a connection between the substantiallyseparate ear and neck portions. The central panel portion 512 of the earportion may be said to comprise said junction, and to carry the neckstraps 514, 516 at a rear end of the portion 512, and also the earportion right and left wings 524, 526, that extend generally transverseto the central panel portion 512 and the central axis of the device. Asin the other embodiments described above, wings 524, 526 are fastenedtogether for installation on the animal, so that the ear portion iswrapped and comfortably tightened around the animal's head, preferablyextending from at or near the largest-diameter of the animal head(typically at the occiput), down over each ear and along each cheek, andaround the throat/under-the-lower-jaw of the animal.

Adjustable strap 550 is supplied on the outside of the ear portion, in asimilar manner as strap 450, but with one end (toward the left in FIG.21) of the strap 550 being permanently attached to the ear portion andwith the other end (toward the right in FIG. 21) being detachable andadjustable relative to the ear portion at hook/loop fastener 552. Thissingle-end adjustment has the same or similar effect as the two-endadjustment straps discussed above, to pull regions of the ear portiontogether for adjusting width of the ear portion for a better fit, inother words, adjusting the distance between the outer extremity ends ofthe wings and adjusting the resulting circumference of the ear portion“loop”.

As discussed above, stiffener/rigidizing members/regions may beimportant for control of the shape and position of the ear portion EPand hence the contact/pressure of the ear portion EP on the ears or oncertain portions of the animal's skin, and/or to prevent rolling-up orscrunching of the ear portion by pawing the ear portion or byrolling/rubbing against the ground or another object. Removable andresilient stiffener plates 513, 513′ are provided in the central panelportion 512, and, as explained below, the removability is important in alongitudinal adjustment system provided for the device 500. As discussedearlier in this document, such resilient stiffener plates are more rigidthan the surrounding material of the device, for example a polymer suchas high density polyethylene, but are slightly bendable to avoid injuryto the animal. Further, additional strips 535, 537 of similar or thesame material as plates 513, 513′ may be sewn or otherwise provided inthe wings 524, 526 to shape the region for optimum protection/retentionof the ears and/or to further prevent said rolling-up or scrunching.Strips 564, 566 may be made of similar or the same material as plates513, 513′ and strips 535, 537, for placement in the neck portion toreinforce and/or stiffen the neck straps 514, 516, for example.

In addition to the adjustable fasteners and resilient stiffenerfeatures, the central panel portion 512 of device 500 additionallyfeatures a longitudinal adjustment system for customizing the length ofthe device 500, along central axis CA″, for different animals. Thecentral panel portion 512 is provided with a bias B1 for shortening thelength of portion 512 along longitudinal central axis CA″, thus,shortening the entire device. In effect, this brings the ear portioncloser to the neck portion, and the front edge of the device closer tothe rear edge of the device. The preferred, but not the only possible,bias is provided by elastic E in/on the central panel portion 512,oriented and elastically-biased in such a way that the elastic tends topull the front end and rear end of the central panel portion 512 towardseach other, as shown by the arrows of bias B1. A seamstress or otherperson of skill in the art will understand how to provide the bias B1 byinstalling one or more pieces of elastic or spring material, forexample, centrally located in portion 512.

Two plates 513, 513′ are inserted into one or more pockets in portion512, with one or more openings into the pocket(s). Preferably, a singlepocket opening P is provided at an end of what amounts to atwo-compartment pocket in the panel. The two compartments 521, 521′ areseparated along most of their lengths by the elastic E and/or stitchingor other structure, but the interiors of both compartments 521,521′ arepreferably accessible through a single opening P. Upon opening of thepocket opening P, preferably by means of an optional latch such as ahook-and-loop fastener HL or other optional closure, plates 513, 513′may be slid into their respective compartments 521, 521′, and theopening P may again be closed/latched. Said sliding the plates 513, 513′fully into their respective compartments 521, 521′, may requirestretching of the central panel portion 512 against the bias of elasticE to accept the full length of the plates 513, 513 and to close theopening P. However, if the plates are shorter than the full length ofthe panel portion 512, the elastic E will maintain the portion 512 in asomewhat shortened configuration, to match the length of the plates 513,513′. In other words, the stiffening plates 513, 513′ work against thebias B1 to prevent the portion 512 from being shortened to the fullextent the bias B1 (such as elastic E) would otherwise accomplish in theabsence of the plates.

Therefore, a user may adjust the length of portion 512, and hence thedistance from the front edge of the device to the device rear edge, bychanging out the plates or cutting the plates (513′, 513) to variouslengths. Use of plates of various lengths will result in elastic pullingand retaining of the portion 512 to be the length of, or generally thelength of, the plates. “Generally the length of” is used here to accountfor the fact that the portion 512 is slightly longer in many embodimentsthan the pockets 521, 521′, due to the additional length of the neckportion at region 522, and of the ear portion at region 523. Preferably,the pockets 521, 521′ extend along 70-98%, or 75-95%, or most preferably70-80% of the length of the portion 512, and the elastic or other biasB1 is adapted to shorten the portion 512, when no opposing force such asinserted plates is applied, by at least 10%, at least 20%, and mostpreferably 15-25% compared to its length with no bias B1 applied. Inmany embodiments for dogs, bias B1 can shorten portion 512 as much as 2inches, which can serve to pull the front edge of the device at and nearthe top of the dog's head rearward as much as 2 inches. Thus, multipleplates 513, 513′ of various lengths may be provided or plates may be cutby the user, so the user may custom-fit the device 500 by insertingselected plates or cut plates to match the animal that will wear thedevice, and then the bias B1, such as the elastic, pulls the centralpanel portion to tighten the plate pocket subcompartments 521, 521′against the ends of the plates 51, 513′, making thepocket/subcompartments a length that generally matches the custom-fitinserted plates. Typically, whatever the plate selection or cut length,the right and left plates will be of the same length, due to the typicalgeneral symmetry of the right and left sides of the animal head.

As shown by the installed device 500 of FIG. 22, portion 512 tends tobend at or near the central axis CA″, so that the two plates 513, 513′lie along-side, but not over, the dog's sagittal crest that runslongitudinally along the top of the dog's head. Lying thus on each sideof the crest/ridge of the dog's head, the plates may pivot to be otherthan co-planar, that is, at an angle to each other (angle AP, FIG. 22),for example, and in certain embodiments pivoting to be at an obtuseangle to each other rather than co-planar, the two plates 513, 513′ tendto stay in place relative to the dog's head and to be comfortable, whilestill accomplishing the desired utility of preventing rolling andscrunching of the device by the dog. Having one plate on each side ofthe sagittal crest, separated by fabric or other soft and flexiblematerials, tends to keep the ear portion centered on the dog's head.

Further, by viewing FIG. 22 and its schematically-shown bias arrows, onemay understand the benefits, bias, and results of the resilientstiffeners and of the length adjustment system of portion 512. Bias B1,by elastic E for example, acts parallel to the central axis CA″ toshorten portion 512, which, due to the fixed connection of the earportion to the neck portion that is secured around the animal's neck,pulls the front edge of the ear portion (and the surrounding frontregions) rearward, for example, the same or about the same as the amountof said shortening of portion 512. Therefore, shortening portion 512 bymeans of a longitudinal adjustment system is beneficial forcustom-fitting the device to a particular dog or other animal, in orderto prevent the front edge (and surrounding front regions) from being in,or interfering with, the dog/animal's vision, which could be aggravatingto the dog/animal. The length adjustment system helps the device to fitthe animal's head, keeping the front edge of the device comfortablybehind the eyes and a neat fit over the sagittal crest.

The resilient bias provided by the stiffeners, such as B2 and B3, causesthe ear portion to “pop back” or “spring back” into place, even if thedog paws or otherwise pushes the ear portion to try to remove it. Thebias B2, provided by a longitudinal “spine” such as plates 513, 513′ isparticularly important for preventing the ear portion from being pawedor pushed back off the ears; multiple plates or stronger plates may beused in this “spine”, for example two stacked plates inserted on eachside of the sagittal crest, for a dog that is determined or strong inhis/her pawing/pushing. Bias B2, acting at least parallel andtransversely to the central axis CA″ and provided by stiffener(s) suchas plate 513, keep the ear portion properly located and orientated onthe head and help prevent interference with said location andorientation by the animal. Bias B3, acting at least parallel andtransverse to the front edge (or, generally, at least parallel andtransversely to the central axis CA″) and provided by stiffener(s) suchas strip 535, also keep the ear portion and especially the front edgeproperly located and orientated on the head and help preventinterference with said location and orientation by the animal.

In FIGS. 21 and 22, it may be noted that the stiffener strips 564, 566in the neck straps are slightly distanced from the plates 513, 513′ inthe central panel portion 512, with fabric of the neck portionin-between. Thus, strips 564, 566 are not attached to, fixed to, orintegral with plates 513, 513′, and gaps G1, G1′ lie between them. Also,it may be noted that the stiffener strips 535, 537 around the front edgeof the ear portion are separated from the plates 513, 513′, with fabricof the ear portion in-between. Thus, the strips 535, 537 are notattached to, fixed to, or integral with plates 513, 513′, but gaps G2,G2′ lie between them. These gaps G1, G1′ G2, G2′ and the flexibility ofthe fabric in the gaps, allows the device to flex at those gaps, forimproving the fit of the device to the animal, and for allowing theanimal wearing the device to move substantially naturally andcomfortably. It will also be understood that other embodiments, such asthose shown in FIGS. 15-19 have similar gaps between stiffeners, forsimilar flexibility of the device and the resulting good fit andmovement and comfort of the animal wearing it.

The preferred device is made as a one-piece protector, that is, the neckportion and ear portion being integral portions of a single “main body”or “main panel” (fixed together and not disconnectable from each other),plus one or more stiffeners installed at the time of manufacturing andnot typically removable, plus one or more stiffeners insertable andchangeable by the user, for example, the plates in the central panelportion. The protector having removable stiffeners may be called a“one-piece” protector because the removable stiffeners typically remaininside the device during use. The protector device main body/main panelmay be made of many different fabrics, for example cold weather or hotweather fabrics, breathable fabrics, water-proof or water-resistantfabrics, soft fabrics and/or smooth fabrics not likely to attract andcatch cheat-grass or fox-tails, for example. Preferably, the protectordevice is washable with or without removal of the plates or otherremovable stiffeners.
